2-Amino-4,5-disubstituted-oxazole/thiazole compounds and antidotes for thiocarbamate, triazine and acetamide herbicides. These antidote compounds are especially effective to safen acetamide herbicides used to control grassy weeds in sorghum and broadleaf weeds in corn.

2-amino-4,5-disubstituted-oxazole/thiazole compounds as herbicide

2-(Heteroamino)-4,5-substituted-oxazole/thiazole compounds are antidotes for thiocarbamate, triazine and acetamide herbicides. These antidote compounds are especially effective to safen acetamide herbicides used to control grassy weeds in sorghum.

2-(Heteroamino)-4,5-substituted-oxazole/thiazole compounds as herbicide

2-chloro-4-trifluoromethyl-5-thiazolecarbothioic acid derivatives having the formula ##STR1## where R is C.sub.1-5 alkyl, phenyl or benzyl, have been found to be effective in reducing herbicidal injury to grain sorghum caused by the application thereto of a 2-haloacetanilide herbicide, especially, alachlor.

2-chloro-4-trifluoromethyl-thiazolecarbothioic acids useful as

2,4-Disubstituted-5-thiazolecarboxylic acids and derivatives thereof have been found to reduce herbicidal injury of corn, rice and sorghum plants due to the application thereto of acetamide herbicides.

Herbicidal composition and method

5-Aryl-4-isothiazolecarboxylic acids have been found to reduce herbicidal injury of rice plants due to the application of 2-chloro-2',6'-diethyl-N-(butoxymethyl)-acetanilide.

5-Aryl-4-isothiazolecarboxylic acids and derivatives

2-chloro-4,5-disubstituted-thiazoles have been found to be effective in reducing herbicidal injury to sorghum plants due to the application thereto of acetanilide and thiocarbamate herbicides.

2-Chloro-4,5-disubstituted-thiazoles useful as herbicidal safeners

2-Chloro-4,5-disubstituted-thiazoles have been found to be effective in reducing herbicidal injury to sorghum plants due to the application thereto of acetanilide and thiocarbamate herbicides.
